Firm, carbon-free power for AI.
AI compute needs power that's always on, clean, and sited where the racks are. MetroVolt is a fusion generator built for exactly that — 24/7, weather-independent, and native to a DC bus.
Power sized for a campus.
Built for the load, not the weather.
Always on
Fusion runs regardless of sun, wind, or season — the firm baseload AI training and inference actually need.
Carbon-free, low-neutron
Low-neutron D–³He fuel (fₙ 5.44%) — a far cleaner profile than D–T, with scheduled-replacement waste near zero.
DC to the rack
Direct energy conversion turns charged products straight into electricity — no steam turbine, and a DC-native output that suits data-center power.
Where the load is
A compact, fixed-site machine you place next to the campus — not tied to a remote resource.
Right-sized
Net power scales with central-cell length — the same locked design at +104 / +850 / +2,832 MW_e.
Vertically integrated
MetroVolt runs on helium-3 the HYPERION breeder makes — one architecture, fuel to firm power.
Closure is requirement-class — it needs an end-plug density we specify and haven't yet demonstrated. We publish that gate, not around it.
Run the numbers.
Power your compute with fusion.
Let's talk about siting, capacity, and timeline for firm, carbon-free power at data-center scale.
